1. A systematic approach for major renovation of residential buildings
Sammanfattning : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. LÄS MER
2. Building Energy Efficiency Measures in District Heating Systems
Sammanfattning : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reducing greenhouse gas emissions and primary energy use. To be able to evaluate how energy refurbishment influences greenhouse gas emissions and primary energy use a wider system perspective is needed which puts the building in its context. LÄS MER
3. Influences from Building Energy Efficiency Refurbishment on a Regional District Heating System
Sammanfattning : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reduce the greenhouse gas emissions caused by human activity and the primary energy use.To be able to evaluate how energy refurbishment influences the greenhouse gas emissions and the primary energy use a wider system perspective is needed that puts the building in its context.

4. Energy System Collaboration as a Vital Measure to Improve District Heating Performance
Sammanfattning : With joint commitments by twenty-seven countries under the Paris Agreement, the European Union envisioned a resource-efficient and competitive economy without net emission of greenhouse gases by 2050. Immediate and massive efforts across sectors of energy, industry, and buildings will be required, and district heating (DH), through its ability to integrate efficiency measures on the supply and demand side, can play a central role.

5. Improved Energy Efficiency in the Aluminium Industry and its Supply Chains
Sammanfattning : Energy is an essential resource in the daily lives of humans. However, the extraction and use of energy has an impact on the environment. The industrial sector accounts for a large share of the global final energy use and greenhouse gas (GHG) emissions. The largest source of industrial GHG emissions is energy use. LÄS MER
